ANSI/AAMI EQ89 (formerly EQ56)
Guidance for the use of medical equipment maintenance strategies and procedures
In plain words
What it covers.
US guidance for building a medical equipment management programme. It explains how to choose a maintenance strategy for each device type, using risk, manufacturer advice and evidence, and how to measure whether maintenance is working. It replaced the older AAMI EQ56 recommended practice.
Who uses it: Clinical engineering managers and healthcare technology management teams.
A summary written by BMEssentia for learning, not the text of the standard. Always work from the current official edition and the manufacturer's instructions.
It covers
- Equipment inventory and inclusion criteria
- Risk-based maintenance strategies
- Use of manufacturer recommendations
- Alternative equipment maintenance (AEM)
- Performance measures
- Documentation
Key points
What engineers need to know.
- Not every device needs the same maintenance: match the strategy to risk and failure evidence.
- High-risk devices usually follow the manufacturer's maintenance recommendations.
- Alternative maintenance plans must be justified with data and documented.
- Measure effectiveness, for example PM yield and failures found that could cause harm.
- Scoring methods such as Fennigkoh-Smith rank devices by function, risk and maintenance needs.
- The inventory must be complete for the programme to be trusted.
